v Specification forming part of `lettera'Patent No. 44,437, datedSeptember 27,1864.

To aZZ whom, it may concern:

Be it known that I, JOHN MAXWELL, of Amsterdam, county ofiMontgomery,and State'- ot' NewYork, have inventeda new and Im- 1 roved Method ofLubricating Knitting- Burrs.; and `I dohereby declare that the followingis 'a full, clear, and exact description thereof, reference being had tothe accompanying drawings, making ai part of this specifi- Figure -l isa top view ot' a knittingLburr having my invention applied toit. Fig. 2is l a diametrieal section through Fig. 1. Fig. 3 is 4a view of the axisaround which the burr ritates.

Similar letters of' reference indicate correy sponding parts 'in thethree figures. l

The objectof my invention is to provide for l keeping the axes ofknitting-burrs always We l oiled with clean oiland intactA from dust andfuzzy substances, which so often clog and cause a drrangement of theknitting ma- 'lhe nature of my invention consists in a tubular axis,around which the burr revolves, and from which it receives its oil, inconjunction with a, cap which is a-ixed to the burr, so as to constitutea cover for the upper end of said axis, as will be hereinafterdescribed.

To enable others skilled in the art to make ,In the accompanyingdrawings, Arepresentsa knitting-burr, which may be made in B representsthe axis around which the burr A revolves, which has a shoulderformed'on shown in Fig. 2. Above this shoulder c the formed is toreceivev cotton or lother suitable spongy substance, which is to-besaturated with oilthat is supplied to the burr through an oriiice, b. xThe 'cotton will absorb the oil' put? -into the tubular axis and supplyit in small quantities to the burr. Surrounding this axis B, and forminga part ofthe burr, is

atube, c, the ends ot' which project short distances from the upper andlower surfaces o' l-tlie burr. The lower end of this tube or bushingrests upon the shoulder a of the axis, and the upper end receives overit a pivoted cap, y, which is connected to the upper face of the burrand turns with it. As thisv cap g is pivoted to the burr in suchrelation to the upper end of the tubular axis as to cover it closely andexclude all dust, 85e., it can be turned aside at any time and theoil-chamber snp pli'ed vvith fresh oil without remoi ing the burr fromitsv axis.

The cap g is made of suchv size as to completely cover the end ot' thetube e; hence nothing can get in around the axis B through oted cap,asliding cap or cover may be used, in which ease itwill be made so as tocover the tube c and exclude dust, die. Y

By this simple arrangement the difficulties attending oiling and keepingthe axes ot' knitting-burrs oiled are removed and neither dust 4 nor theilyings escaping from the yarn will in any way interfere with the freerunning ot' V'the burr.

Having thus described my invention, what I claim as new, and desire tosecure by Letters Patent, is-

1. The application of a movable cover, g, to

a knittingburr having a tubular oil-supplying axis, about which the burrrevolves, substantially as described.

2. The combination of a cap, g, tube c, and tubular spindle or axis Bwith a knitting-burr, 'substantially as described. i

3. The combination of shoulder a and tubulargaxis B with a knittiugburrhaving a cap applied toit for closing said axis,-substantial]y4A asdescribed.

JOHN MAXWELL.
